Specification of Letters Patent.

App'iieation fried February zo, 191s. serial No. 749,616.

concern Be it known that citizen of the United States, residing at Sag Harbor, in the county of Suffolk and vState of New York, have invented certainv new and useful Improvements in Geometrical Machines, of which the following is a speciication, reference being had therein to the accompanying drawings, which form a part thereof. i

My invention relates to geometrical machines, and more particularly to a machine adapted to create intricate designs, by means vof a master bearing a simple outline,

having as a whole no resemblance to the design to be created or prozduced.

vThe main object of the invention is to produce mechanically, from an elementary outline, character or base, in itself simple, an Vintricate design or geometrical figure having as a whole, no similitude to the elementary outline, character or base.

A further object is to provide a machine Vfor creating geometrical designs from a simple elementary outline, character or base, Vwhich is capable of such adjustment asto permita large number of entirely dissimilar geometrical designs to be produced from a single elementary outline, character or base. A still further object is to provide a machine for lcreating geometrical designs from a simple elementary outline, character or which machine during a single sewill create and superquence of operations,

two dissimilar impose' one upon the other, line designs. y. l

A still further objectJ is to provide a machine for creating intricate geometrical designs or figures from a simple elementary outline, character or base, which machine vwill be so constructed andarranged as to operate with great accuracy and with a certainty which will not require expert knowledge of machinery, nor any skill in drafting or engraving. e j

A stillfurther obj ect is to provide a machine which may be operated continuously 1 byY a sequence offsimil'ar operations to create or produce any geometrical design.

A stillr further object is to provide a machine capable of use to producev metallic plates for engraving purposes, Vprepare metallic `plates for acid etching, or make matrices adapted for use in making cameo or intaglio line safety designs for negotiable instruments.

A still further object is to provide a machine adapted to create intricate rosettefdesigns in which the operation of the machine instead of being purely mechanical is variable as determined by a master or element having indicated thereon an elementary outline, character or base, the coniguration Vof which and the adjustable relation of the Patented J an. 4, 1916. l l

master or element to other coperating elei 1 ments of the machine will determine the character of the rosette, thus eliminating the purely mechanical nature of the design and minimizing likelihood of duplication thereof,

A still further obj ect is to provide a mai chine of this lcharacter wherein the operation of the machine, irrespective of the nature of the design to be created, will always be the same, the compelling or controlling means acting entirely independent, and

without the control, of the operator of the e machine.

'A still further object is to provide a machine of this character wherein a plurality of different compelling or controlling means may be interchangeably used upon the machine and adjustments may be made in a manner to vary the character of the created design at the will of the operator, thus presenting additional elements of safety and preventing duplication or reproduction of the design, even with a similar machine, unless the exact setting of the compelling or controlling element and other adjustments are known to the operator.

A still further object is to provide a ma. chine wherein the spacing of the lines may be varied, thus not only varying the design, but adapting the machine to dierentclasses of work. And a still further object is to provide a machine which will be simple in its design and mode of operation, and capas ble of quick and accurate adjustment to sea plurality of similar outlines upon a workz v plate or sheet, and means adapted to -vary Ythe relative position ofv said outline, charthereof; Fig. 3'is a plan view in detail of the 4controlling; or compelling mechanism by means of which the movements `of the support for the means carrying the elementary outline, character or base are defined,

' 11 and l2 aredetail views illustrating some different elemetary outlines, characters or bases which may be used;

Like numerals refer to like parts throughout the several views.

' In the 'accompanying drawings, I have shown an embodiment of my invention which includes therein the essential characteristics of a well known type `of pantographic engraving machine, which in actuall use I'have found to give highly satisfactory results. This machine, however, is merely typical of a large number of machines in which my improvement may be incorporated, and if desired, still other and special designs of machines adapted for special uses may be constructed so as to embody the essential characteristics of my invention. f

In lthe following description, I have ref ferred more particularly to the particular type of machine shown in the drawings, it being expressly understood, however, that it is not myintention to in any way limit mechanisms for defined by the character Vor base, to

transmitting movement as elementary outline,

the mechanism by which the Vdesign is produced. i i

My invention isespecially adapted for i use in creatingdesign's for, or upon printing plates, and plates, or matricesffor use in v developing printing plates, which designs are 1n the form of rosettes or other iny tricate geometricaldesigns, to be used in connection with the production of safety papers such as are used in bank notes, negotiable mined ysible, with the old pafpers or instruments. Heretofore, these sa ety designs have been either made by hand or upon a rose engine or'engine lathe, the design resulting from certain predetermechanical movementsA in the machine itself. By this means, a limited number-of designs only could be produced, and

uthe safety factor was limited by the known capacity of the machine. Growing out of this condition, it has heretofore been the custom'to develop `a part of the design by machine and the balance` by hand. A `rose engine is capable only of producing scroll work, and if it be desired to include in the white line safety elements of a note, paper y or instrument, an element other thana scroll,

such as is usually found in bank notes, this is always done by hand. The old method of producingsafety designs referred to required a period of from two to ten weeks, or more of expensive, high class skilled labor, and as I have heretofore stated, the designs created in most instances were all modlfcations of one general design.

y my improved mechanism, I am enabled to secure intricate geometrical designs, susceptible of practically infinitevariations, each of which designs will be complete in itself and, when a plate is made upon a machine, will require no hand nishing. I am also enabled to mechanically superimpose one design upon another, or insert a number or word design in the body of a scroll work design. I am also enabled to make a proof design and a completed designin a materially shorter timethan is posrose engine and hand work method. i y

In theform ofthe invention shown in the accompanying drawings, l indicates a central column carrying a bed plate "2 for a movable table 3 ada ted` to carry the sheet or plate .upon whichl the design is to be formed. Said column is mounted upon the main table 4 of the machine which may be supported in any desired manner. The table 3 isy mounted to have universal movement upon a single plane so as to place no limitation upon the movement thereof, and thus permit the formation of strai ht -or curved lines in 'any direction. At 5` have shown a steadying mechanism to insure absolute accuracy `1n the movement of the work supporting table 3. At 6 are-ball bearinr mounts for the table 3 which insure abso utefreedom ofv movement. Mounted upon the column 1 above the work table 3 is a supporting means, as the oscillatory arm 7for a work point 8 which in the form -of the invention shown is an ordinary graver. The oscillating work point carrying arm is controlled by the link, treadle and lever mechanism 9, this point being adapted to be brought` into contact withthe work surface through gravity only.

. ting it and a Y f. of reproducing means,

. Mounted by means of a universal joint 10 and a vertically adjustable collar 11 upon the column 1, is a transmitter 12, one end of which is adapted to have mounted therein a tracing point or stylus 13, and the other end of which is connected by means of a universal joint, not shown, with the work table 3.

' The adjustability'of the collar 11 is for the purpose of varying the range of movement of the table as compared with that of the tracing point or stylus. Carried by the work table 3 is a work support 14 having means whereby a plate or sheet may be attached thereto, which means are adapted to be released to permit the adjustment of thel plate or sheet on said table to secure the proper placing of the design on said plate or sheet.

In Fig. 6 I have sho-wn a rotary spindle 15, and old and well known means for setfor apredetermined depth of out, lever mechanism 16, by means of which the work point or routing tool is brought into engagement with the work. By this means a cameo or an intaglio plate may be accurately produced which plate may be used as a master plate from which transfer rolls may be made, or the plate itself may after hardening, beV used for undersurface printing.

The mechanism above described has been heretofore patented to me and it is not my Vintentionr to claim such mechanism broadly at this time. Theelements above referred to constitute one type of pantographic engraving machine embodying one'character the mode of operation of which contemplates the exact reproduction of a design or pattern upon any desired scale. By my present invention, however, kl do not reproduce a fixed design, but vary the operation of the above described mechanism in a manner whereby a design is created which as a whole bears absolutely no resemblance tothe original design or master. a support for the master or element having thereon an elementary outline, character or base, which support is capable ofV movement ,asy defined by an actuating mechanism, and a controlling plate which determines the general character of the outline ofthe rosette or other design, although by adjustments provided, this outline itselfmay be varied.

The actuating mechanism comprises a rotary kbase 17, mounted upon the main bed 4 yals of the machine and having mounted thereon a slide 18, capable of movement radially of thejcenter of rotation thereof. This base is acted upon by the weight 19, through the cord 20 which. weight has the function of aidingV in that rotary movement of the base which will be hereinafter referred to.

This mechanism comprises Surrounding the base 17 is a rim 21, adapted to receive a controlling or cam plate 22, having an opening therein defining the extent and direction of movement of the slide 18. The configuration of the opening through the plate 22 may be varied infinitely, (examples of such variations being shown in Figs. 7 to 9), thus making it possible to vary infinitely the general character of the outline of the geometrical design to be created. y

The slide 18 carries za contact pin 23 adapted to be forced into engagement with the edge of the opening in the plate 22 by the springs 24 acting upon said slide, thus imparting to said slide 4with the rotation of the Vbase 17, an eccentric movement due to the simultaneous rotary movement of said slide and its lineal traverse under the control of said springs and said controlling plate. To secure the desired movement of the slide 18 means are provided for imparting a rotary movement to said base, which means operate simultaneously with the means imparting lineal movement to said slide, that is the springs 24f'and the controlling plate 22. This actuating mechanism comprises a ratchet wheel Y25 formed on or carried by the base 17, which ratchetl is acted upon by the spring pressed detent dog 26 and the actuating dog 27 carried lby the oscillatory plate 28 rotatably mounted upon a pivot in the base 17.

The function of the dog 26 is to prevent a return movement of the base upon the return oscillation of the plate 28. The dog 26 is provided with a lock pin 29-by means of which this dog may be disengaged from the ratchet to facilitate the restoration of the base 17 to normal. Y rThe movement of the said plate 28 is guided by a slot therein through which a portion of the rim 21 projects, this plate having movement beneath other portions of said wall.

Adjacent to the operating handle 30 of the plate 28, I provide an adjustable stop comprising a pin 31 adapted to be mounted in any one of a series of graduated openings carried by the stop plate 32.

The controlling plate 22 is detachably mounted upon the rim 21 so that said plate may be removed at any time and another plate having a different design of opening substituted therefor to vary the character of the design to becreated, or the position of the plate upon the rim 21A may be changed.

127, which adjustment, however slight, lwill have the eifect of varying the character of the design created either as to its general outline, or its center design. The bearing pin 23 is also capable'of adjustment upon vthe slide 18, the holes 34` at opposite ends thereof being provided so as to vary the radial position of this pin relative to the center of rotation of the base 17.

By the mechanism heretofore described, I am enabled to vary not only the relative positio-n of the support for the elementary :youtline, character or base, `and the Workbed, but also the relative position of the work bed and the work point, thus causing said point to operate upon a different portion of the plate, sheet or body carried by said Work bed, this variance causing an outline similar to said elementary outline, character orbase to be successively described upon different portions ofthe work plate or sheet.

Hence, variance in the design created from any elementary outline, character orrbase, may be accomplishedeither by the substitution of one contro-lling plate for another having an opening of dissimilar' configuration, by a changeof position of said outline, character or base upon the slide, or by a change ofthe position of the slide relative to the center of rotation of the base 17 .and to the controlling plate through the adjustment or change in position of the contact `pin 23. A still further variance in the appearance of ythe design, Without, however,

changing its general character, may be accomplished by means of the stop p1n 31,

' the positionof which will control the number of .lines entering into the created design 'and their spacing. The design may be still further'modified by accomplishing any of these adjustments during the operation of developing the design. i

In Figs. 10 to 12, I have shown three illustrative outlines, characters or bases, other than that shown in Fig. 3, and as these themselves may be varied infinitely, it can be readily understood that the number of designs which may be created is infinite, and yet, whatever the nature of the design createdthe movements of the operator and lof the operative parts of the machine are always Vthe same, varying merely in degree, in some instances.- i Y* The eccentricities of the machine are so i pronounced that even with a definite outline,

character or base,- anda `definite controlling plate, -it is impossible to determine what the i controlling plate itself.

character of the created design will be, or what theformation of the center` of the design will be, and this uncertainty is also present with every adjustment of vthe machine, irrespective of a change of the elementary outline, character or base, or of the In fact, to duplicate a givendesign, it is necessary to record or element carrying the elementary outline,

character or base as consisting of a metallic plate .35 havinga single line geometrical gure. cut thereinto so as to form a guide for thetracing ,point or stylus 13, and the work plate 36 upon which the design is to be created as a prepared plate adapted to have portions thereof removed by the graver, although in no sense am I limited to the use of such.`

Throughout this specification when referring to an elementary outline,character or base, I contemplate a geometrical figure or an incomplete geometrical ligure as distinguished from mere straight or curved lines, the outline of which figure taken `as a base and repeatedly reproduced in the manner determined by the controlling or `compelling mechanism will create, form or constitute the completed intricate geometrical design. i i

By the term Work plate orsheet as used in the specification, I contemplate a metallic plate from which portions of the metal are to be actually removed; a copper plate coated with resist to be removed preparatory to an acid etching process; proof glass or paper upon which a design may be made to determine the suitability thereof before making a' plate; matrices from which a cast is to be made, or any other substance or material adapted to receive in any manner whatsoever, a design. By the term Work point. isto be included any instrument orimplement for marking, cutting or scratching upon any material. y

The operation of the herein described machine is substantially as follows z-Before beginning Work with the machine, the controlling or compelling cam plate 22 is first secured upon the rim 21 in the desired position. Byproviding the rim 2l with regularly spaced screw holes, said cam plate maybe shifted around in any desired position upon said rim. The master or element 35 is then mounted upon the slide 18 in the desired relation to the center of rotation of .the support 17, said slide" 18 being provided ico tobe placed 'in operation.

work bed 14, being' so placed thereon that the design to be'created vwill appear in the proper position upon this plate. The positioning of this plate does not in any way aiect the character of the design produced or created. The tracing point or stylus 13 is then brought into position relative to any point of the elementary outline, character or base, and the treadle mechanism 9 actuated to bring the Work point into engagement with kthe work plate or sheet 36. When the parts are in this position, the tracing point or stylus 13 is moved completely around the elementary outline, character or base, and brought to rest at its starting point. Thereafter either with or without actuating the treadle mechanism 29, the lever 28 is actuated, rotating the support 17 and slide 18, and changing the position of theslide 18 to an extent defined by the controlling or compelling plate 22. The actuation of the lever 28, therefore, has the two-` fold function yof varying'the relative position of the elementary outline, character or base and the work plate or sheet, and of spacing the successive line reproductions of said elementary outline, character or base in the created design. .1f the work point be raised from the work plate or sheet, the outline of the figure willrbe interrupted, or formed of `a series of sections the character of each of which will be defined by the configuration of an end of the elementary outline, character or base. If, however, the work point be held in engagement with the work plate or sheet, the outline of the created design will be dened by a continuous Y line connecting the series of sections above i referred to,

or a part thereof only, according to the setting of the machine. The alternate tracing of the elementary outline, character or base, and actuation of the lever 28 is repeated until the rotary support 17 and itsy slide 18 reach the starting point ink operating the machine, or until the desired depth of cut in the lines of the design is secured, when the material of the work plate or sheet 4itself is to be removed. The controlling plate 22-has the effect of imparting to the slide 18 movement toward` or from the center of rotation of' the support 17 to an extent controlled by the contour or configurationof the .cut out portion of said plate,

Vbut while this plate22 will absolutely determine and control the movements of the slide 18', the outline of the created design and its dimensions will not necessarily be the same as thel outlines of the'cut out portion ofthis plate', nor are the dimensions alwaysthe same, as the' adjustment of the elementary master or element 35 upon the slide 18 will varyboththe character of the outline, body and center v design kofthe created design, and its dimensions. For instance,fif the elementary master or element 35 be set upon the slide 18 close to the bearing pin 23, and entirely upon one side of the centerl ofv rotation of the support 17, the outline of the created design will be substantially the same as the outline of the` opening in the plate 22, and the dimensions of said design will be large. Also when the said master or element is so set, the lines upon the designV may or may not intersect the center of the created design, (according to the dimensions of the elementary outline, character or base), thus producing one character of center. If, however, the said master plate or element be set closer to or with the major portion thereof only upon one side ofthe center of-rotation of the support 17, the outline will remain the same as before but the lines will intersect each other and the center of the design at different points, and by extending upon the opposite sides ofthis central point, modify this design about the center, thus creating an en tirely dierent design, although one having the same general outline. Y

When the quantity of movement of the slide 18 under the control of the plate 22 is small, that end of the elementary outline, character or base most removed from the center of rotation of the plate 17 and adj acent, or toward, the pin 23, will always describe the outline of the created design. 1f, however, the quantity of movement im-k parted by the plate 22 be great, at some point of the design, one end of the elementary outline, character or base'may be made by the setting of the plate 35, to describe an outline dissimilar to any portion of the controlling plateV and at another point the other end thereof will describe the outline. This eccentricity will create a design wherein not only the center will be extremely complicated, but the outline itself, unless the masterA or element bearing the elementary outline, character or base be set close to the pin 23, will have absolutely no similarity to the configurationof the cut out portion of the controlling plate. lf, however, the master plate or element be set so as to bring the elementary outline, character or base, either wholly or in major part upon that side ofthe center of .rotation opposite that of the bearing pin 23, the effect will be an outline in the created design which will possess no similarity to the designof the cut out portion of the controlling plate22, although the center of themfigure may bear some resemblance to the out out portion of rsaid plate. Thevexplanation of this is that the outline of thecreated design will ordinarily be defined by that portionv or end ofthe elementary outline, character or base which isclosest to thecut out portion of the plate 22; Hence when the master orl element 35 is mounted. wholly or inmajor part upon that sideof the center of rotation of the support 17: toward thebearingV pin 23, the changes of position of the parts of the elementary outline, character or base nearer to the said plate 22, will accord with the movements of the slide under the control of the plate 22. In other words, if the slide 18 move outwardly, the master plate or element will also move outwardly or away from thecenter of rotation of the support 17;', andto an extent defined by said plate 22. If, however, the said masterl or element be upon the other side of the center of ro`` tation of the support 17, as the pin 23 and slide 18 move outwardly or away from the center of rotation of said support 17, under the Control of the plate 22,'the yportion of the elementary outline, character or base forming thek outline of the created design instead of movin' outwardly from the center` of rotation o `the support 17 will move toward said center of rotation, orvice versa, and thus not coincide with the configuration of the cut out portion of the 4plate '22.

i This difference is further accentuated by the changes in the point of intersection of the numerous hnes. Under some conditions a portion of the elementary outline, character or base will form a portion of the center of the design, and at points of the design it will project beyond the normal outline of the created design and thus form a part of the outline of the design Whichis particularly noticeable in controlling plates wherein the cut out portion isof a configuration to impart sufficient movement'to the slide 18 to cause the major portion of the elementary outline, character or base to be first on one side of the center of rotation of the support 17 and then on the other side thereof. This will'be readily understood from Vthe fact that that portion of the design which at any time isclosest to the controlling plate 22 will constitute the outline of the created design and with a constant'shifting` of the slide- 18, one end of the elementary outline, character or base may at one time be close to said plate while at other times another portion of said elementary outline, character or base may be close thereto.

Fromthe foregoing, it becomes apparent that the created design in outline will coinieo cide or differ with or' from the configuration of the cut out portion orcam surface of the plate 22, according to the q uantitx7 of movement of the slide under the control of said plate and the location'of the master plate or element carrying Vthe elementary outline, character or base, upon this slide.

Ordinarily if the master or element carrying the elementary outline, character or base is set so thatits vcenterfcoin'cides with the center of rotation of the support17, and

y the controlling plate 22 hasr a svmmetrical opening therein, the yresultingfigure in outlie. will. oieeidefwith. theoafguretien. 0f

ideaal? said opening, but the setting of the said master or element upon either side of the center will vary its outline to an extent which may be determined only by the actual operation of the machine.

Heretofore I have referred merely to the effect of the controlling plate 22 upon the outline of the created figure, but it must` be understood that with every adjustment of the machine heretofore referred to, even though the outline of the created figure may be the same as the configuration of the opening in the plate 22, the innumerable intersecting lines in the body of the created figure w1ll form a large number of minute figures, which figures constitute the body of the created design. Each of the minute iigures and the tone of the center of the design will change with every v ariance in the adjustment of the machine irrespective of any change in the general outline. This is due to the fact that there will be a change of the angle and point of intersection of the numerous lines with each adjustment of the machine. By these adjustments the tone of thercenter of the design also maybe changed, an increase in the dimensions of the created design generally resulting in a dark cen-c` ter in the design created, and a reduction in these dimensionsresulting in a light center. When the pin 23 is shifted inposition to vary the dimensions of the created design, or the plate 35 is so adjusted for the same purpose, the character of the center will always change, .while the character of the outline may ormay not change, according to the extent of the adjustment.

The scale of the created design may be varied by using a plate 22 having a smaller similar opening, and a proportionately smaller elementary c outline, character or base, or when my improvements are used upon a pantographic machinethe scale may be varied by the ordinary pantographic adjustments. By either of these methods, any created design may be reproduced in the manner heretofore described, but on a different scale; the outline, body design and center being unchanged excepting as to di-` mensions. j

By setting the master or element carrying the elementary outline, character or base entirely `upon one side of the center `or rotation of the support 17 a simple design will 4result from the actuation of the machine. If, however, portions of the elementary outline, character or base are upon opposite sides of the center' of rotation of4 said support, a complex design is the result, one design being superimposed upon the other. These designs will be dissimilar inasmuchr as the movement of the portion `of the design` upon one side ofthe center of rotation will be awav therefrom. at the same timethatfthe portion upon the other side will be toward said center. 4VThe superimposed design may rangeV from two designs substantially of the same dimensions as each other, to a large design, with a dissimilar and smaller design extending about the center'of the created figure.v When it is desired to superimpose a still different design upon a created design, it is merely necessary to remove one master or element, substitute another'therefore and repeat the operations of the machine, or if desired, when a differentfigure, as a numeral or a word is to be thus superimposed, a master of vthis niimeral or word may be substituted for the elementary outline, character or base, and the machine used as an ordinary pantograph.

vIf it be desired to .vary the spacing of the lines 'in a design, it is merely necessary to change the location of the pin 31.

The pin 29 may be used to disengage the pawl 26 from the ratchet 25 to permit the rewinding of the pull cord 20 upon the support 17. Y

If'desired, the pin 23 may be shifted from adjacent one end of the slide 18 to adjacent the" other endv of said slide, and the springs 24 reversed, thus entirely changing the outline and character of the designwithout the necessityl for shifting Vthe master orv element 35.

By the foregoing description, itis apparent tliatan infinite number -of different designs may be created by reason lof the differ ent manner in which the machine may be adjusted and the interchangeability of controlling or cam plates, and masters or ele.- ments, of 'different configuration; and that whatever the configurationof the controlling plate, operation of the machine consists solely in causing the stylus 18 to follow the elementary outline, character or base,

and the partial. rotation of the support v17` to an extent determined by the mechanism ofthe machine'. By these two operations practised alternately, the most intricate and complex de signs may be created by labor totally unskilled in engraving or drafting, and in a fraction of a day, work may be completed which under the old methods would require Y weeks.

In the accompanying drawings, I have shown merely one embodiment of my invention, and it is apparent that the structure therein shown may be varied indefinitely without departing fromthe spirit and scope ofthe invention'.

An essential of the machine is the employment of an elementary outline, character or base, aplate, sheet or body upon which the design is to be created, a. reproducing mechanismacting as defined by said elementary outline, character or base, and describing af similar outline upon saidplate, sheet kor body, and means .varying'the relative posior the master orv element,` the tion of the're'producin'g 'means and the work plate or'sheet so as to portion of thev former portions of the latter. Various mechanisms may be employed for accomplishing this result, and in the accompanying drawings I have shown but one such mechanism. The elementary outline, character or base may be a Vseparate part of the machine, or may appear directly upon the support therefor.

I believe it to be broadly new to provide a machine wherein an intricate geometrical design may be created mechanically from a mere simple elementary outline, and I intend to claim such broadly.
